Why unable to instantiate application?

Question

I'm frustrated by this kind of problem, and tried to find all solutions but failed. Please someone who did solved this kindly give me some advice, thank you.

mainifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    
package="my.package.name"    
android:installLocation="internalOnly"    
android:versionCode="15"    
android:versionName="v8">    

<application        
android:name="my.package.name.App"        
android:icon="@drawable/app_icon"        
android:label="@string/label"        
android:theme="@style/FullBleedTheme"        
tools:replace="android:label"        
android:usesCleartextTraffic="true"        >

App.java:

public class App extends BaseApplication {        

  private static final String TAG = App.class.getSimpleName();     

  public void onCreate() {        
    super.onCreate();

google play crash log:

Please double check your packagename in manifest or paste it here at least. Maybe its not pointing to correct packagename. Or you put it on separate subpackage. — Marka A, Sep 16 '14 at 02:17

Turn off the instant run in android studio. Then build and run. It will work. It worked for me.
